Atwell makes a perfect femme fatale-cum-special agent, and this '40s noir-style short looks great and packs some euphoric action moments (which raised whoops from the first-look audience). Carter is a brilliant heroine who could likely carry her own movie. Whether there’s a space for expansion, or whether they’d consider a retro S.H.I.E.L.D. spin-off or not, it seems clear that Marvel’s got a ready-made female superhero waiting in its ranks.
